Don Pianta, also known as the Don of Untimely Death, is the boss of the Pianta Syndicate as well as ruler of the wealthy district in Koopa City. Since his promotion to Governor by King Bowser, he leaves his direct subordinate Frankie to manage the Syndicate in his stead. Frankie also happens to be the husband of Don Pianta's daughter. The Don spends most of his time in his mansion surrounded by his goons and often grants an audience to people looking for favors. Favors that people have to repay. Those that defy the Don learn firsthand why he's called the Don of Untimely Death. All things considered, his presence in the city has been a good thing overall. The smaller crime rackets have been forced out, the city's kept clean, and the only murders being committed are by the Don himself. So all in all, things are pretty good.

As the person in charge of security, he's also in charge of judging those suspected of disrupting the harmony. Violent cases go through him, and his judgments are swift but fair. He keeps order in the court through intimidation, but it gets the job done. In court he's a no-nonsense judge and doesn't have time for your nonsense. If you can't behave, you will be forcibly escorted out. No debates, no discussions. In the rare case of murder trials, the sentence is always death.
